Hello folks, It's a long time since I've been around these parts, 2 nicely running W203's means that I don't really frequent as much as I should. How that has just changed ! Last week the serpentine belt idler pulley was making a racket.. to be fair it's been grumbling for a LONG time but rather than fix it as it wasn't a major issue I ignored it.. to my error. Last week mrs was driving the AMG and the steering went dead heavy, smell of rubber and a light came on the dash saying "Battery / Alternator Visit workshop". The long grumbling bearing had given up the ghost and ceased. Anyways cut a story short... Water pump, idler and pulley were replaced and got the car back last night. However the garage (Indy) have left the car with the bloody error "Battery / Alternator visit workshop" and even put the error on my sodding invoice saying it needs investigation... WTF !!! Any ideas on what would cause this ? Hoping not a buggered alternator as I've already for a bill for about 600 notes. Much appreciated.
